Leners Patent Nt. 97,623, dated December 7, 1869.

i IMPRVBMENT n r CARRIAGE-mns.

- The Schedule `referred to in these Letters Patent and making part of the same.

Be` it` known that I, SAMUEL FoRREsTER, of the city and county of Allegheny, and State of Pennsyl vania, have invented anew and useful Improvement in Spindles for Axles of Garl'iages and Wagons; and I do hereby declare that the following isa full, clear, and exact description thereof',` reference being had to the accompanying drawings, and to the letters of reference marked thereon.

','lhe nature of my invention consists in securing a cast-iron or steely spindle on the axlecf a carriage or wagon, .by Vforming the core of the spindle 4and the endofthe axlein such a manner and form as to leave a space around the axle, which space is ,lled with a metal or alloy, after-adjnsting-the spindle on the axle, the whole constructed as" hereinafter described.

To enable others skilled in the art to make and, usev my invention, I will4 proceed to describe its construction.

i In the accompanyingdraiv/jngsu, Awhich forni part of my specication- `Fignresl Iis a side View ofmy `improvement in spindle. for axles 'of-carriages, Sac.

Eigure2 is `a longitudinal section of the same.

Figure 3 is a'transverse section-of the same, when outer endof i Whichis made tapering in form, with an indentation at and-a projecting shoulder at xr rlhe spindle Bis provided with a clip llan'ge, o',

which is used in connection with the clip j, for binding thewood G and-the inner end of the spindle to the axle A.

Th'e spindle B is cored out, so as to leave the space m, around the axle A, withv a cavity, c, for the projecting shoulder X on the axle. Y

` l represents the llnchpin.

'n represents an opening leading into the space ai.

Having all things constructed, as bereinbefore described, the spindle B is adjusted on the axle A, and held, by means of the Wedge h and clip j', in the desired position; the molten metal or' alloy is then .poured into the space 'm through the opening n,

thereby securing the axle firmly and securely in the spindle'. v

By this mode.o'i"securing the spindle on the axle, the jarring and krattling of the spindle on the axle are avoided,- and va perfect fit of theraxle in the spindle is always secured, thereby obtaining greater strength Y ofthe several-parts .with relation to each other Having thusdescribed the nature, construction, and operation of my improvement,

What I claim, as of myinvention, is-

The projection x, when used in combination with cavity e, in the spindle B, wedge h, and the metal lor allo'y filling, as herein describe dand for thev purpose set forth.
